Linux is an OS, which is not that widely used for desktop machines, but is one of the most popular OSs for web servers. It's 100 % free, so you shall not need to pay any license charges as part of your web hosting payments. Linux is additionally thought of as the most reliable Operating System these days and due to the permissions which files have and the file types that can be run, virus files that could infect a standard personal computer will simply not be executed on a Linux-based server. Moreover, the Operating System is absolutely free, so it could be customized without any limitations, as a way to meet the requirements of the hosting company and their customers. This also suggests that unnecessary software packages may be removed to make the OS lighter and faster, which can directly lead to significantly better server performance. Lots of Linux machines have the Apache web server installed on them, since this software is also free, fast and stable. It's the most commonly used web server around and is a part of the LAMP bundle that a lot of script apps, including Joomla™ and WordPress, require. LAMP is an abbreviation for Linux, Apache, MySQL and PHP.
